Was able to try the Kim Possible game earlier this year at Epcot and that got me thinking. Is this type of interaction the future for theme parks?

Sort of like the evolution from movies to videogames. First, you watch the movies, now you're a chracter in the movie when playing a videogame.

Especially now with Harry Potter land opening and every kid getting their own wand similar to kim possible, the park operators know the guest and can tailor the experience to them. I've always felt this be the natural evolution of theme parks in that the guest becomes a "cast member" themselves so to speak. Like to hear other people's thoughts on this.
